Abstract: Let $R$ be a prime ring of $\operatorname{char}R\ne2$, let $d$ be a nonzero derivation of $R$, and let $\rho$ be a nonzero right ideal of $R$ such that $[[d(x)x^n,d(y)]_m,[y,x]_s]^t=0$ for all $x,y\in\rho$, where $n\ge1$, $m\ge0$, $s\ge0$, and $t\ge1$ are fixed integers. If $[\rho,\rho]\rho\ne0$ then $d(\rho)\rho=0$.

Keywords: prime ring, derivation, extended centroid, Martindale quotient ring.
